Also, a Fox News VP declared the McCain/Palin campaign "over" if this proved to be a hoax, given the involvement of race-baiting by a representative of the campaign. Heck, both McCain and Palin even alled the fabricator without waiting to see whether the story played out as true first.
UPDATE: Josh Marshall weighs in as only he can:
To say this is a dark moment does not do justice to the deep awfulness of this stunt. It's the metaphoric pedal-to-the-medal for the sleazy sub-rosa campaign of racial fear-mongering that so far has failed to derail Obama's candidacy.
There are many questions to be asked about who pushed this story yesterday afternoon and last night. A lot of explaining.
UPDATE: CC's Mack believes that the fabricator was put up to the hoax by the campaign.
